LED blossom everywhere in the middle and lower growth rate

Consumer daily news, after years of development, China's LED industry chain has become increasingly perfect, companies spread over the LED substrate, LED epitaxy, LED chip, LED packaging and LED applications in various sectors. Throughout the industrial chain, due to the upstream industry for higher technology and capital requirements, resulting in domestic enterprises rarely involved, so there is a small number of enterprises in the industry, the characteristics of small scale.

In contrast, because the downstream packaging and application to business of financial and technical requirements are relatively low, which is precisely the domestic enterprises and less capital, technology weak character matching, therefore, a large number of domestic enterprises engaged in the two sectors. This uneven distribution of enterprise structure led to China's LED industry is dominated by low-end products, enterprises face severe price pressure for a long time.

With the sharp decline in the cost of these two years LED upstream epitaxial chip, upstream epitaxial chip, midstream packaging, downstream applications have formed a scale of 1:4:9 market size. From the upstream investment situation, extension investment growth fell from 46% in 2012 to 10% in 2011, while investment in downstream applications of growth in 2011 was 21%, 2012 increased to 53%, so the LED industry investment focus from upstream to downstream transfer.

The upper part of the high technical content, large capital investment, the quality of the impact of large, high profit space, material and process of LED light color and luminous efficiency and production of LED, and the upstream LED accounted for about 70% of the manufacturing cost, which plays an important role in the LED industry; the middle is technology and capital intensive sectors, the chip is currently patent competition the most intense link, with large investment intensity but slow characteristics; downstream links including LED packaging and lighting application development and production, and the market is most closely linked to the link, technical content is relatively low, the investment threshold is low, so it is the size of the LED industry in the largest and fastest growing areas.

In the upper reaches of the LED epitaxial wafer, chip production, the United States, Japan, the European Union still has a huge technological advantage, while China's Taiwan region has become the world's important LED production base. The world has formed the industry pattern in the United States, Asia and Europe as the leading and showing to a situation of tripartite confrontation, Japan and the United States, Germany as the industry leader, Chinese Taiwan, followed by South Korea, Chinese echelon distribution of mainland China and Malaysia and other countries and regions actively follow up.

Although the international advanced level there is a certain gap in the distance China LED epitaxial wafer and chip production technology, but domestic demand for large, to LED downstream manufacturers to bring tremendous opportunities for development, domestic production such as display, landscape lighting and other LED application products have been exported to the United States, the European Union and other countries and regions.

At present, the main chip extension, research institutions have Peking University and Tsinghua University, Nanchang University, Institute of semiconductors, physics, electric 13, Southern China Normal University, Beijing University, Shenzhen University, Shandong University, Nanjing University, the main technology solution on silicon substrate GaN epitaxial growth layer, GaN based blue light wavelength drift and improve the internal quantum efficiency and the light emitting efficiency, improve the anti decay ability and power chip heat dissipation level and so on.
